Hang Seng Plummets: Biggest Monthly Drop Since March 2026

The Hang Seng Index has experienced a significant downturn, marking its largest one-month point and percentage decline since March 2026, with a current monthly drop of 2.30%. This volatility continues a trend, as the index has now fallen in six of the past eight months. The past week saw a considerable 1.65% decrease, the steepest since the week ending March 6, 2026. This decline snapped a three-trading-day losing streak and contributed to a sustained period of losses.

Over the last three weeks, the Hang Seng Index has fallen 1211.32 points, a 4.59% decrease, representing the most substantial three-week drop since the period ending March 20, 2026. The index has also been down five of the past six weeks. Despite this broader downward trend, today's trading session saw a positive turn with a 176.23-point, or 0.70% gain, the largest single-day increase since May 22, 2026. Year-to-date, the index is down 448.15 points, or 1.75%. It remains 24.04% below its record close set in January 2018 and 9.96% off its 52-week high from January 2026.
